II. HULL PART

1. HULL STRUCTURE

Higher tensile steels (up to Yield Point of 315 N/mm² and 355 N/mm²) can be used in longitudinal structures in the lower part of the hull girder, but shall not make up more than 15% of the hull steel weight.

Plating in ballast tanks shall be a minimum of 11 mm for primary structure and 10 mm for secondary structure. Shell plating shall be a minimum of 12 mm thickness to provide long life and good strength against damage from contact and waves. Innerbottom plating shall be a minimum of 12 mm to provide for longer life. Shell plate in way of anchor rub area shall be increased by 5 mm thickness above the minimum class requirements.

Permissible loads and scantlings shall be in accordance with the rules of the Classification Society. Local strength of main deck aft to be sufficient for container stack loads of 40 mt for 20’ containers or 50 mt each for 40’ containers. In addition, the main deck aft, in way of where cargo loading is possible, shall be designed for general cargo loads of 1.0 mt/m² (200 psf). RoRo space shall have deck strength for loading of 1.25 mt/m² (250 psf).

Allowable bending moments and shear forces shall be such that there is at least a 5% margin over the envelope of actual bending moment and shear force values from any expected combination of loading in ballast and with cargo. These loading combinations should include a full load in the RoRo space with full container stowage.

Primary framing system of the hull structure shall be longitudinal with transverse web frames and bulkheads arranged as shown on the General Arrangement Plan.

Integrity of fire zone boundary bulkheads shall be maintained for the full depth of the vessel and bulkheads shall be kept in one plane to the extent possible. Penetrations through watertight and fire zone boundary bulkheads shall be minimized and shall not exceed the quantities allowed by the applicable Rules and Regulations. Closing mechanisms for doors through these bulkheads shall be remotely operable. All vertical and horizontal trunks for piping, ducts and electrical cable shall be insulated with A-60 insulation where required by SOLAS or Class Rules.

Primary deck longitudinal support structure in the deckhouse and hull shall align with pillars fitted vertically in line from top to bottom of the vessel. Full extent of steel bulkheads shall be utilized to support structure in decks above to minimize use of pillars in accommodation spaces. Stair towers and vertical trunks shall be aligned with primary longitudinal structure so that they can be effective in supporting deck structure. In the RoRo space, installation of pillars shall be minimized.

The stern frame and rudder horn shall be constructed of fabricated welded steel in conjunction with steel castings and designed to obtain adequate clearances for the propeller. Propeller shall be removable without drawing in the tailshaft or removing the rudder. Stern tube cooling water tank is to be provided in the lower part of the Aft Peak.



Rudder is to be of twisted shape, double plate, spade type with flap, Becker or similar. It shall be capable of rotating to 45 degrees to either side plus an additional 45 degrees flap rotation, while in maneuvering conditions (10 knots or less). Maximum turning shall be 35 degrees to either side above 10 knots. For Becker rudder, the Becker Intelligent Monitoring System shall be provided to show rudder force with display on the bridge.

The stem area above the bulb, because of its narrow beam, shall utilize closing plate type construction with welding of the closing shell plate from the exterior only. The stem area with this construction, where internal access is not possible, shall be a watertight void space with appropriate anti-corrosion coating. Provide drain plug in the bottom stringer of the void space to check for water leakage into the void space.

Tug pushing areas shall be provided, two each side, in way of transverse bulkheads and one on CL on the transom with required local strengthening. The tug push areas on each side shall have a vertical extent at least from 1m above the light draft to 3m above the load line draft, and a horizontal extent of at least 2 full web frame spaces.

Bilge keels are to be fitted through about 25% of the ship's length amidship.

Piping mains shall be run above the inner bottom rather than in a pipe tunnel in the double bottom. Pipes for systems that can lead to flooding of spaces shall be inboard of B/5 in general, as required by the Rules and Regulations.

A Bulwark shall be arranged on the main deck forward of the deckhouse as shown on the General Arrangement Plan.

Deckhouse exterior boundary walls to be of plane construction with internal vertical stiffeners. Inside division bulkheads to be of vertically stiffened flat type or swage type where not visible from the passageway. The arrangement of internal webs, pillars and steel bulkheads shall be specially designed to minimize vibration within the deckhouse. Where the deckhouse sides align with the side shell below, smooth transitions with large radius shall be fitted at any openings (such as for the lifeboats) and at the ends of the house, as shown on the General Arrangement drawing. Inside the deckhouse, bulkhead plating shall be a minimum of 7 mm and deck plating shall be a minimum of 8 mm exterior and 7 mm interior.

The RoRo deck (3rd deck) shall not act as the top of a tank so as to avoid manholes and vent pipes intruding into the main part of the RoRo deck. Piping and fittings can be installed on the RoRo deck within the extent of the shell and bulkhead framing. Any voids or cofferdams above tanks shall have a minimum depth of 1.3 m to allow easy passage through the void for inspection.

Openings in way of the side shell for the RoRo side ramp, stores sideports and quarterdeck access shall be fitted with generous radius and proper compensation fitted where needed to maintain the strength of the hull.

Finite element structural analysis shall be carried out in conformance with Class Rules and shall include a detailed analysis of the transition areas from the hull to the deckhouse side and in way of openings in the side shell. Vibration analysis shall be carried out for the after part of the hull and shall include confirmation that the deckhouse has adequate structural support and stiffness against excessive vibration.
